.ToZZ whomJ it my concern;

Be it knowny that, GEORGE II. CONANT, a citizen of the United States, residing at Min- Minnesota, have invented certain new anduseful Improvements in -Dump Weighing- Scales, of which the following is a description, reference being hadto the accompany-y ing drawingsandtothe letters of reference marked thereon. y y v My invention relates to that class of weighing #-i scales commonly known as dumpscales, which arev usedy for weighing grain in wagons and then dumping the` load eitherthrough an opening vin the platform or over the end of the scale.

The objects of the invention are to provide a construction in which there shall be as large a space as possible between the scale-levers, so that there will be ample room for the dump(v sticks to swing down, and also to provide a, scale lever mechanism not liable to affect the accuracyof thescale .should the foundation get out of level by the settling of the building, dto. These objects I accomplish by the construction illustrated in the accompanying drawings, in which* Figure l is a front elevation of a scale hav- .ing my improvements applied. Fig. 2 is a plan thereof with part of vthe planking removed. Fig. 3 is aplan of the lever mechanism. Fig. 4 is a side elevation ofthe klever mechanism. Fig. `isa cross-section online 5 5, Fig. 2. Fig. 6 is a section on line 6 6, Fig. 2. Fig. 7 is a detail perspective of the connection between the transmitting-lever and its underlying connecting-lever, and Fig. 8 is a similar view of the meeting ends of a pair of the multiplying-levers.

A designates the supporting-framework, and B the scale-platform, on which a're pivoted at b b the ytwo dump-sticks B B. C represents the weigh-beam mechanism, O' its operating-rod, land C2 the supporting-standard. All of the above-described 4mechanism is constructed and operates in the usual manner and need not be further described. Moreover, I have omitted the mechanism for operating the dump-sticks, as nothing is claimed thereon. f

D designates the transmitting-lever, pivot- SerialNo. 53,890. (No model.)

allyl connectedat its free end to thelowerend of vertical rod C'by means of a link d, and the opposite end rof said lever isfulcrumed on a link d on the lower vend of a vertical bolt d2, mounted onV frameA opposite the Astandard C2.

The lever D is provided near itsr free end with a vertical opening cl3 andl near its middle with a horizontal opening d4. f

E is the connecting-lever.underlying -the transmitting=lever D between its two openings d3 d4 and fulcru med atone end on the lower end of a bolt e, which is mounted on'the frame A,

near its standard C2, While a box-link e. connects the free end of this leverE with the lever D through the opening d4, asclearly shown in.l

ed together, as shown in Fig. 8, by box-link F2, a second 1ink,f, extending' up through the top cross-pieceof each link F2 and hung, re

spectively, on the levers D E, (see Fig. 5,) near their fulcrumv-points. The levers F F' are provided with conical points f f2, the pointy bearing on the lower cross-piece of link 2 and the point f2 bearing on the lower cross-piece of link'f. 1

The outer ends of the levers F F are fulcrumed onfthe lower ends of bolts g, carried by the diagonal brackets G, bolted in the four corners of the frame A, as shown in Figs. l and 2. The four corners of the scale-platform B are provided with depending yokeelikebrackets H,througl1 which freely pass the said levers F F', (see Fig. 6,) and thelevers sust-ain the Weight of the platform through the medium of the pairs of links h h, the latter being engaged by the lower end ofyokes H.

It has been found that by connecting the multiplying-levers to the rod C by means of the levers D' E instead of by a pipe-lever or torsion-lever, as heretofore, the accuracy of the scale is not aected by the settling of the frame, like where the pipe-lever is employed.
